It's still not very clean as we still lock the mvapi_btl mutex inside a critical section
protected by the endpoint mutex ...

- Remove printing of CFLAGS in configure.m4
- Set MCA_BTL_FLAGS_SEND flag
- Improved error handling during module initialization
- Extract the address of each interface with dat_ia_query
- Start playing around with fragment stuff - probably wrong
- Misc code cleanup (removal of GM-specific code)

new wrapper compilers for the OMPI layer. This should require no changes
at all for anyone (other than running autogen, of course)

know that the request is inactive we don't have to call fini). Remove if's from
the critical path. Change a do in while to make sure we do the minimum in all cases.
All in all it decrease the latency for mvapi by something between 0.15 and 0.20
micro-seconds. But it's just a first step ...

increased the datatype ref count, and there is no way to have a convertor without a valid
request, so there is no need for the convertor to increase the reference count of the datatype
again. Therefore, if one want to use the datatype for something else than MPI request, one
has to manage the reference counts outside the datatype layer.

thread finish a request between the moment when we check the request status and the moment
when we acquire the lock, and if there are no more pending request on the pipe we will be
stuck foreverr as nobody have any reason to broadcast the request condition. I check the
req_any and it doesn't contain the same bug.

makes illegal free() calls behave in a much more rational way. You'll still
probably die, but your stack trace will not have 3 billion pages of recusion
inside the memory allocator.
* Fix illegal free in the opal_wrapper code. basename() returns a string in a
static buffer, so it shouldn't be free()ed. It also shouldn't be left around
so long, as another call to basename() may whack the returned buffer. So
leave the free and add a strdup() around the basename() call.
* Turn off some unneeded debugging in the opal_wrapper code that would list the
comamnd to be run, regardless of the -showme option.

A small and ugly workaround the path problem on windows (the absolute
path start with [a-z]: whn : is considered as separator for most of
the environment variables.

the descriptors to vanish. The PML was thinking that they are in the btl_cache when they
weren't ... It lead to memory consumption on most environments when compiled with
thread enabled. After modification the latency went down by nearly 0.5 microseconds.
Simple way to trigger the bug: limit the number of maximum items in the free list and run
any communication intensive application (like Netpipe).
